I am new to javascript. Hence, I would like to know if there is an idiomatic manner to remove duplicate lists on a list of lists.

Example:

let arr1=[1, 2];
let arr2=[1, 2];
let arr3=[1, 2, 4];
let arr4=[1, 2, 3, 4, 5];

in_arr=[arr1, arr2, arr3, arr4]

// remove repeated lists function

function removeArrayDuplicates(in_arr){
    return 42
}

// let out_arr=removeDuplicates(in_arr)

out_arr=[arr1, arr3, arr4]

console.log(out_arr);

Best regards.
